Summary

Food restriction programs improved feed conversion (FC) in broiler chickens. Reducing feed intake by 10% or 20% enhanced FC without negatively impacting daily weight gain (DWG), uniformity, or mortality.

Area of Science:

Animal Science
Poultry Nutrition
Zootechnical Performance

Background:

The poultry industry prioritizes improving zootechnical indexes like feed conversion (FC) and daily weight gain (DWG).
Rising feed costs necessitate exploring strategies such as food restriction programs to enhance efficiency and profitability.
Food restriction has emerged as a potential method to optimize broiler performance and mitigate economic challenges.

Purpose of the Study:

To evaluate the impact of two distinct food restriction programs on broiler zootechnical indexes.
To determine if reducing feed intake by 10% or 20% affects feed conversion, daily weight gain, uniformity, and mortality.
To assess the efficacy of food restriction in improving broiler performance metrics.

Main Methods:

One hundred eighty male broiler chickens, aged 10 days, were housed in 12 boxes for 30 days.
Three treatment groups were established: control (recommended intake), 10% feed reduction, and 20% feed reduction.
Zootechnical indexes including feed conversion (FC), daily weight gain (DWG), uniformity, and mortality were measured and compared.

Main Results:

No significant differences in daily weight gain (DWG), uniformity, or mortality were observed among the treatment groups.
A statistically significant improvement in feed conversion (FC) was noted, with a gain of 100 g for the 10% reduction group and 252 g for the 20% reduction group compared to the control.
Food restriction programs positively influenced feed conversion without adverse effects on other key performance indicators.

Conclusions:

Food restriction programs are effective in enhancing feed conversion (FC) in broiler chickens.
Implementing food restriction at 10% or 20% reduction levels does not compromise daily weight gain (DWG), uniformity, or mortality.
These findings suggest that strategic food restriction can be a valuable tool for improving the economic efficiency of broiler production.
